Juno notably sent the first infrared close-ups of the planet’s north and south poles.

“These first infrared views of Jupiter’s north and south poles are revealing warm and hot spots that have never been seen before," said Alberto Adriani, of the Istituto di Astrofisica e Planetologia Spaziali in Rome.

Adriani is one of the researchers who developed the Jovian Infrared Auroral Mapper (JIRAM) that allowed scientists to acquire the images.

“While we knew that the first-ever infrared views of Jupiter’s south pole could reveal the planet’s southern aurora, we were amazed to see it for the first time," he said.

Auroras are streamers of light in the sky caused by energy from the sun and electrically charged particles trapped in the magnetic field.

Another Juno instrument recorded sounds from Jupiter — “ghostly-sounding transmissions emanating from the planet," said Nasa.

Scientists have known about Jupiter’s radio emissions since the 1950s, but had never analyzed them from such a close distance.

“Jupiter is talking to us in a way only gas-giant worlds can," said Bill Kurth, co-investigator from the University of Iowa.

Juno’s main mission began in July and is scheduled to end in February 2018, when the probe will self-destruct by diving into the planet’s atmosphere.

The $1.1 billion project aims to peer beneath the clouds around Jupiter for the first time to learn more about the planet’s atmosphere.

Scientists want to know how much water the planet contains, because it can tell them a lot about when and how the planet formed.

Juno will also probe how the planet’s intense magnetic field is generated, and study the formation of auroras.
